I was working on a tiny business card sized booklet for a client, only 50x90mm. Each page had an icon and some text to go with it. Of course, they had tons of text to go on each page, and I wasn’t allowed to use more than one page for each bit.
Me: I really can’t fit that much info into each page. Maybe you could cut down each page a little?
Client: Oh, we can’t do that. What font size are you using?
Me: It’s 8pt, I’m really not comfortable taking it any smaller than that if you want people to be able to read it.
Client: *thinks about it* Just increase it to 9 pt, that should give us enough room to fit some pictures under the text too.
I don’t think my client has the best grasp on how space works.
